2005 gmc canyon just started blowing smoke out tail pipe
2005 gmc canyon just started blowing smoke out tail pipe but it doesn't do it every time i start it. is this bad It just started its only happened twice blowing smoke out the tail pipe, its not getting hot or using oil or missing just when i started it it had smoke coming from tail pipe. Possibly a leak in the head gasket. Take out the plugs and see if they are water wet. Run a compression check.
